The File Copy Test - Windows consists of creating 9006 files totaling a size of 1060MB. The creation, read, and copy tests were performed with the graph differentiating which is which.



From the test above, I would expect the Raptors to outperform the other drives in the benchmark, but it didn't do it by much. In fact, I was surprised that the WD4000KD out performed the WD2500KS in this test. Both drives buffer to disk specification are the same, rated at 748Mb/s



Here is a real shocker; this drive outperforms my Raptors in RAID 0. Coming in with the highest read speed for this test is a definite plus. Mind you, this is no fluke. All these tests were conducted a minimum of 3 times with reboots and defrags between each of them. The results are then averaged out to get the score you see.



This test demonstrates more of what I would expect from our Raptors. As you can see, this drive nudges out its "faster" sibling, the WD2500KS.


The File Copy Test - Programs consists of creating 8504 files totaling a size of 1380MB.



This drive is performing very nicely compared to the other drives.



This drive is continuing to impress me with its read scores in these tests. A thing to note is that this is copying and reading a TON of small files. You will see that things change later on when we start to get to the bigger files.



That is one close score. I had to rerun this test 5 times to just be sure. This drive came in just a horse's hair behind the fastest of the drives in the copy test.
